clean_tmp_areas does a find -atime +1 on /tmp. This does not detect the case
of files moved to /tmp in the past day which were not accessed in the last
day. I have verified that mv preserves access/modify times even when copying
across filesystems. Therefore, it is not safe to store files in /tmp around
4:20 AM unless you have looked at them within the past day (A user recently
had the bad luck to be logged in at 4:20, with two big files temporarily in
/tmp, both of which he had not looked at recently. They were erased.)
I can't find a flag to find to check the inode change time, but that is a
good double check if it can be done.
